LASTING-li/IACHINE.

SPECIFICATION forming part of Letters Patent No. 696,740, dated April 1,1 902.

Application filed April 19,1900.

To all whom it may concern:

Be it known that I, SHERMAN Vv'. LADD, of Beverly, county of Essex,Commonwealth of Massachusetts, have invented certain Improvements inLasting-lvlachines, of which the following, read in connection with theaccompanying drawings, is a specification.

In the present instance this invention is represented and described inconnection with to the machine of United States Letters Patent No.584,744:, whereto reference is made for matters not herein fully setforth and described.

Figs. 9, 10, and 11 are sectional planviews representing different operative positions of the mechanismswhereto this invention in part is related. Fig. 12 is an elevation ofparts shown in Fig. 9. Figs. 13 and 14 are perspective views showingdetails connected with Fig. 12.

From Letters Patent No. 584,744, cited above, it will be learned thatthe boot or shoe is prepared for the lasting operations by suitablyarranging the last, upper, lining, &c., and overdrawing the upper at thetoe and along the ball at each side of the last and there fastening ittothe inner sole by a tack or similar fastening device in each of saidplaces. Asingle pair of pincers is employed to which the boot or shoe ispresented and turned about by the workman, the lasting op eration as awhole being carried out progressively by repeated operations of themachine applied to different parts of the upper at different times.Tack-supplying and driving mechanisms are employed whereby the partSerial. No. 18,453. (No model.)

of the upper acted upon by the machine at one time is secured in placeto the inner sole preliminary to the next operation of the machine.

In the machineas herein represented mechanism is employed whereby wireor a similarly continuous material is placed progressivelyin bindingrelation with the successivelylasted parts of the upper, particularlyabout the toe portion of the shoe, said wire being then secured in placeand thereafter serving in place of said tacks for holding saidmanipulated parts of said upper against displacement.

It may be stated here that this invention in part relates to means forsuspending the insertion of said tacks during the time of saidwire-placing operations of said machine and, further, in part to meansfor variably controlling the tension of said wire and to means forshifting the wire-placing mechanism. into and out of operativepositions.

In carrying out this invention a reel 2 is employed for holding wire 20in bulk. Said reel being mounted to turn on a stud in the frame 13 hasits motion retarded to a limited degree by frictional resistance betweenthe spring actuated plunger 4 and the end face 6 of said frame B. Therod 10 permits movement end- Wise in frame B and has screw-threadedengagement with nut 12. Between nut 12 and a collar 14., loosely mountedon said rod, is a spring 16, operating on collar 14 and through itforcing downwardly the flanged drum 18. The wire 20, going forwardlyfrom reel 2,

passes around the drum 18 normally in between collar 22, supported onframe B, and

the flange of drum 18, where it is gripped by tension of spring 16, saidgripping tension being variable adjustably by suitably operating the nut12. Attached to the rod 10 is a rod 26, having connection with lever 28,whereby the workman may further operate the downward movement of rod 10,and consequently vary the grip or tension on wire 20 at any momentduring the machines operations. The

cutter member 30 has support on frame B, its cooperating member 32 beingon rod 10. Movement of lever 28, forcing downwardly the rod 10, operatesthe cutters 30 32 for cutting the wire 20-, which tothat end is placedtherebetween by the workman when desired;

Said machine also comprises the pressers 36 38. Description of theconstruction "and operation of said pressers may he found in saidLetters Patent No. 584,744. It is to be noted here that said pressersnormally stand in a retracted inoperative position, from which-positionthey are advanced to the operative position whenever desired for use. Inuse one of said pressers is'made to rest upon the part of the uppermanipulated by the last operation of said machine, while said otherpresser is in the next operation of the machine moved forwardly to pressinto place the next-adjacent part of the upper. The wire 20, beingfastened by the workman to tack d, is held by the support 40 in suitableposition for hearing upon and binding the parts of said upper which arebeing operated upon by the said pressers. The shoe is turned and shiftedstep by step for successively presenting the different parts of saidupper to the machine-uppermanipulating members, whereby the said upperis manipulated progressively from tack cl to tack e. In this operationthe wire 20 is drawn from reel 2 normally under tension, which tensionis variable by the workman at will by suitably operating thetreadle-lever 28. The said manipulated sections of said upper are inthis manner tied down by the wire 20, which wire is then made fast tothe tack e by the workman, who thereupon positions the shoe with wire 20in cutters 3O 32 and operates said cutters for cutting off the sectionof said wire which has been used to bind the upper.

shown in Fig. 2 operates a movement of rod 42, as required for puttingthe wire-supporter 40 into operative position,and simultaneouslyoperates an advance of pressers 36 38 into working position, withpresser 36 stationary and presser 38 movable. Reversely moving the slide46 to the position shown in Fig. 3 operates a movement of rod 42, asrequired for'putting supporter 40 in inoperative position, andsimultaneously retracts the pressers 36 38 to inoperative position.-Such endwise movements of slide 46 are effected by the workman at willthrough means described in said Letters Patent No. 584,744. In themachine of said patent provision is also made for movement of slide 46endwise beyond the position shown in Fig. 3 in order to advance thepressers into workingposition,with presser 38 stationary and presser 36movable, and in order to permit such movement to take placewithoutchanging the position of supporter 40 the cam-groove 48 isextended from the point occupied by roll 52 in said Fig. 3 in a linewith the said endwise movement of slide 46.

On reference to said Patent No. 584,744 it will be seen that the machineof that patent has provision for plaiting or crimping the upper whendesired by the workman. It is usual to perform these plaiting operationsonly when lasting the toe portion of the shoe, and since the mechanismin which I have chosen to embody my invention in the present instance isadapted particularly for use in lasting the toe portion of the upper Ihave connected the wire-placing mechanism with the mechanism for causingsaid plaiting operations, whereby the wire-placing mechanism is renderedoperative when the plaiting operations are taking place. It hasheretofore been the usual practice in lasting the toe por- I tion of theshoe on the machine of said patent to begin at the center of the toeportion and to last from that point around to one side of the toe-as,for instance, to the point d, Figs. 2 and 4and then to return to thecenter of the toe and last from the center around to the other side ofthe toe to substantially the point e in said figures. In lasting the toeportion in this manner it is desirable to plait or crimp the upper, asfully explained in-said patent, and in the machine of said patent andother machines of the same type it has been customary to accomplish thisplaiting or crimping by moving the pincers laterally or turning thepincers, or both, while the upper is gripped by the pincers. When thetoe portion is lasted from the center of the toe to either side, asabove explained, it is necessary ordesirable to turn the pincers or movethem to one side when lasting from the center to one side of the toe andto the other side when lasting from the center to the other side of thetoe. In the form in which I prefer to embody my invention the toeportion is preferably lasted from one side of the toe around to theother sideas, for instance, from point d, Figs. 2 and 4, around to thepoint e-and in this operation it .is-obviously preferable that theplaiting or crimping mechanism shall operate only in one way, and themechanism herein shown is adapted to operate in that way. As is clearlyshown in the said Patent No. 584,744, the slide 46 is connected with themechanism which controlsthe plait-- ing or crimping of the upper, andwhen the parts are in the position shown in Fig. 2 the machine isadapted to plait the upper in the proper manner during the operation oflasting the tee from the point d around to the point e. Inasmuch,however, as it may be desired to turn or move the pincers to plait theupper in the opposite direction without 7 putting the wire-placingmechanism in operative position, I have in the machine herein shownprovided means. whereby said plaiting can be effected without puttingthe wireplacing mechanism in operative position. In

the form herein illustrated this means includes the slide 46, which, asalready explained, when it is moved to the left, viewing Fig. 3, intothe position shown in Fig. 2, moves forward the wire-supporter 10 intothe position shown in Fig. 2, but which when moved to the right of theposition shown in Fig. 3, as it will be moved when the plaiting istaking place in the opposite direction, will not put the wire-supporter4.0 in operative position, as already explained.

From said Letters Patent No. 58$,7M it may be learned that said machinecomprises means for distributing different-sized tacks along diderentraceways into a single receptacle wherefrom to be driven at different operations of said machine, the size of tack to be driven at a givenoperation of said machine being governed by theraceway which .duringsuch operation of said machine is in communication with the avenue tosaid receptacle, said machine further comprising means forshifting saidraceways,whereby one or another is placed in position for deliveringtacks to the said receptacle according to the size of tack most desired,but in all cases delivering a tack from one or another of said racewaysto be driven at each complete opcration of said machine.

It has been made a feature of this invention to provide means forintercepting the delivery of tacks to said receptacle during a number ofrepeated operations of the machine, whereby the inserting of tacks maybe suspended when, as above described, the wire 20 is employed forretaining the manipulated parts of said upper against displacement. Inthis connection lever 60 has its toothed end in mesh with arotatively-movable pinion 62. The rod 64 has one end attached to theraceway-block 82, its other end being in screw-threaded connection withpart 68. Said part 68 has an opening 70, wherein is journaled thesection 72 of part 74. In part 7-1 is an eccentric hole 78 for receivingthe stud 81, on which is also said pinion 62, said stud being supportedin frame 13.

It will now be understood that a movement of lever 60 to the positionshown in Fig. 9 (the handle 80 of part 74 being positioned as in saidFig. 9) will operate the raceway-block 82 for placing raceway 84 incommunication with opening 86 and allow for passage of tacks from saidraceway 84 through said opening 86 into the tack-receiving chamber ofthe receptacle above mentioned. A movement of lever 60 to position shownin Fig. 11 may be efiected (the position of said handle SObeing thesame) for placing the raceway-block S2 in position with raceway 90 incommunication with opening 86. Said movements of lever 60 are normal tothe machine of said Patent No. 584,744: for shifting said racewayblockand other machine parts, as in said patent more fully described. Now byplacing the handle 80in position, as shown inFig. 10, the part 74. isrelatively placed with said raceways 8% and 90 both out of communicationwith opening 86. No tacks will then pass into said opening 86, andconsequently the machine thereafter continues its operation withoutinserting any tacks. ment of handle 80 to the position shown in Figs. 9and 11 again places the parts in position for the operation of lever 60,alreadydescribed, to cause the presentation of different-sized tacks.The different positions of handle 80 are yieldingly maintained by thespring-actuated plunger 94:, seated in grooves 96 and 98 of part 68.
